Rip timers values
According to the documentation timers basic has five arguments "timers basic update invalid
holddown flush [sleeptime]"
•The rate (time in seconds between updates) at which routing updates are sent
•The interval of time (in seconds) after which a route is declared invalid
•The interval (in seconds) during which routing information regarding better paths is suppressed
•The amount of time (in seconds) that must pass before a route is removed from the routing table
Is it correct to always calculate the flush time as (update interval + holdtime) = flush time
•The amount of time for which routing updates will be postponed
example: "timers basic 5 15 15 20" or "timers basic 7 10 10 17"
